The residence time distribution of an ideal CSTR is
YOUR ANSWER : ?
YOUR ANSWER : ?
Which of the following does not produce a change in the value of rate constant of a reaction?
YOUR ANSWER : ?
A CSTR is to be designed in which an exothermic liquid phase first order reaction of the type, A → R, is taking place. The reactor is to be provided with a jacket in which coolant is flowing. Following data is given: CA0= 5 kmole/m³ ; XA = 0.5; Feed temperature = reactor temperature = 40°C. Rate constant at 40°C = 1 min⁻¹ ; (ΔH) = - 40kJ/mole; ρ = 1000kg/m³ CP = 4 J/gm.°C ; q = 10⁻³ m³/min (ρ and CP are same for the reactant and product streams). The amount of heat to be removed is
YOUR ANSWER : ?
The rate of the chemical reaction A → B doubles as the concentration of A i.e.., CA is doubled. If rate of reaction is proportional to CAn, then what is the value of n for this reaction?
YOUR ANSWER : ?
A batch adiabatic reactor at an initial temperature of 373°K is being used for the reaction, A → B. Assume the heat of reaction is - 1kJ/mole at 373°K and heat capacity of both A and B to be constant and equal to 50J/mole.K. The temperature rise after a conversion of 0.5 will be
YOUR ANSWER : ?
If the time required for half change is inversely proportional to the square of initial concentration and the velocity depends on the units in which the concentration term is expressed, then the order of reaction is
YOUR ANSWER : ?
With decrease in temperature, the equilibrium conversion of a reversible endother- mic reaction
YOUR ANSWER : ?
Which of the following resistances is not involved in a gas phase catalytic (gas- solid) reaction?
YOUR ANSWER : ?
Pure A in gas phase enters a reactor 50% of this A is converted to B through the reaction, A 3B. Mole fraction of A in the exit stream is
